急~!!! 安装libpcap遇到的问题~！！！
执行./configure之后，最后几行如下：
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h
config.status: config.h is unchanged
config.status: executing default-1 commands
请问这个正常么？
继续 make，前面都正常，最后报错：
In file included from /usr/include/asm/system.h:4,
from pcap-ring.c:34:

这是什么问题呀~？？？
[解决办法]
LOCK_PREFIX这个没定义.
去看看readme文件怎么说的,可能是有些选项没加上
